SPECIFICATION forming part of Letters Patent'No. 329,2'79, datedOctober 27, 1885.

Application mea May 21, 1885. seri-.n No. 166,819. (No modera To a/ZZ whom it may concern:

Be it known that I, GEORGE W. COPELAND, of Malden, inthe county of Middlesex and State of Massachusetts, acitizen of the United States, have invented a new and useful Improvement in Heel-Lasting Devices, of which the following .is a full, clear, and exact de-- scription, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature, in w-hich- Figurel is a side elevation of a machine containing thefeatures of my invention.` Fig. 2 is a plan view thereof'. Fig. 3 is a'plan view ofthe abutments or jaws hereinafter described. Fig. 4 is a vertical section upon the line :l: x' of Fig. 2, showing additionally in elevation a lasting-tool hereinafter described. Fig. 5 is a vertical section upon the line y y of Fig. 3. Fig. 6 is a vertical section illustrating a modifled construction hereinafter referred to. Fig. 7 represents in elevation a device for moving the abutments with considerable pressure against the heel end of the last connected or secured to the plate carrying them to the jack or support for holding the last. Fig. 8 is a' section upon the line zz of Fig. 7. Fig. 9 is a vertical section of a last with the upper fitted -t'hereto and a form of abutment especially adapted for right and left lasts. Fig. l() shows in plan view an abutment formed from a flexible sheet of metal adapted to be brought into contact with the heel end of the last by the forward and closing movement of its front ends. Fig. 11 is a vertical section of a last with the upper mounted thereon and an abutment comprising a yielding or flexible metal plate held by springs supported by a suitable block or back.

The invention relates especially to means for lasting the heel of a boot or shoe, and it comprises devices which I have hereinafter called jaws or abutments, which are adapted to be brought inv contact with the side surfaces of `the heel end of the vlast upon any desirable level to compress or clamp the upper firmly thereto, and which abutment-s or jaws also extend above the upper level of the insole to act or assist, in connection with the lasting tool or device hereinafter described, in holding the upper along the edge of the insole while its margin or edge is'being folded upon the surface of the insole and fastened. It also relates to aspecial device or tool adapt- .to fit varying sizes.

ed to be used in connection with said jaws or abutments for the purpose of breaking down, folding, or fitting the margin of the upper upon the insole while it is held clamped against the surface of the last and the edge of the insole.

Referring to the drawings, A A represent the abutments. They may be made of metal or any other suitable material, and preferably they are adapted to be opened and closed laterally in relation to each other to adapt them In Figs. 1 and 2 I have represented this form of construction, the abutments being supported upon the ends of the arms a, a', which are pivoted at a2 and moved by means of the curved slots a3 in the lever a4 and the pins a5, which project upward from the arms into the slots. The inner surface of the abutments conform to the curvature of the heel ,end of the last, and I prefer thatwhen mounted upon the arms a a they be so secured thereto as to have a slight horizontal swinging movement therein upon the centers as. The jaws may have upon their inner surface the flexible metal plate B,Which spans the joint or space b between them; or, in lieu of making the jaws of metal, they may be made of hard rubber, gutta-percha, or any material which can be easily molded or shaped to approximate the form of the heel end of the last. The inner upper corners, c, of the abutments or jaws are cut away, as represented in Fig. 4, for, the purpose hereinafter indicated. The arms a. a and the lever a4 are mounted upon t-he plate d, which is movable horizontally upon the carriage D or upper end of the post d', a ;d this post is vertically movable in the standard or support d by means of the treadle d3 and cord d4, which passes over the pulley d5, or in any other desirable way. The standard or support for the post d is attached lto the plate E, which carries or supports the jack c for holding the last, and this plate is supported or secured to any suitable table or bracket.

In use the upper is mounted upon the last and the last placed upon the jack. The abutments are moved up against the heel end of the last, so that they are caused to close or shut upon the heel portion or section of the upper from a point adjacent to one shank entirely around the shoe to the other shank, and

extending from the insole downward as faras desirable. These abutments are brought with considerable force or pressure upon the heel end of the last, so as to clamp the upper, stiffenings, lining, &c., firmly thereto, and this.

causes the margin of the upper, stiffening, and lining to occupy t-he position represented at the right hand of Fig. 4-that is, the upper, stiiening, and lining will extend upward between the insole and the jawor abutment in a It is then folded over and broken down or fitted to the insole by means of the tool F, (represented in'Fi g. 4,) or any substantial equivalent therefor. rl-his tool comprises a block of metal,which preferably has the smooth working surface f and corrugated surface f, and it is introduced between the outer surface of the upper and the inner edge of the jaw, as represented in Fig. 4:, and then pressed downward to fold the edge of the upper, stiening, or lining upon the edge of the insole; and when pressure or force is needed to obtain a good fitting of these parts the folding device, after it has been used as above described, is struck by a mallet or hammer. This device, it will be seen, knocks down and folds the upwardly-extending edge of the upper, &c.,in sections, and when it is folded over and knocked down and fitted the edge is secured in place to the insole by tacks or other fastenings, and the fastening may proceed as the edges are folded over. In an application of even date herewith I have shown a tool specially adapted for this purpose.

I would state that I do not confine myself to the especial form or manner of making the abutment, o r to the material of which it is made, or to the manner of operating the same, the object of the invention being to provide a clamping device which shall holdthe upper, stiffening, lining, &c., atthe heel end of the last, clamped against the side surface thereof during the operation of breaking down, folding, and fitting and fastening the margin of the upper to the insole; and in an application of even date herewith I have described a process of lasting the heels of boots vand shoes which includes a portion of this mechanism. When the abutment is made of molded material G, (see Fig. 6,) I prefer to support it by an iron or metal support, G', shaped substantially as represented in said figure, and to so mold and shape the abutment to be supported thereby and removable therefrom.

In Fig. 7 I-representa construction in which the abutments are drawn against the heel Aend of the last by means of thelinks H, attached to the plate d, and the lever h, pivoted to the jack at h. Fig. 8 represents a section of this construction upon the line z z of Fig. 7. This construction affords means for forcibly drawing the abutment against the heel end of the last.

In Fig. 9 I show the abutments provided with the upper bearings, M, the lower bearings, M, and the intermediate elastic or yielding cheeks or bearing-pieces, m. This construction is especially applicable for use with right and left lasts, as I have found that right and left lasts are so nearly alike upon the lines or surface acted upon by the solid bearings of the abutments that the same abutments can be used for both right and left lasts, provided there is interposeda space between said surfaces which may or may not be filled with elastic material or cheek.

In Figs. 10 and l1 I have shown still another modification, the jaw or abutment being of spring metal N,which is shaped toconform to the surface of the last, and is held up against the same either by the springs a, which project,or are held by the metal block or support n. Ihe upper edge, n2, of the plate projects above the upper surface of the insole, and is turned outward, as represented in the figures; l

In Fig. 10 I show, instead of the block, the front corners, n3, of the plate as connected or secured to the links oz,which are operated by the arms or levers a a.

In operation the levers are separated to draw out or spread apart the ends ofthe plate, the heel eud of the last inserted in place, and the Nlevers then closed, bringing the central portion, a5, of the plate in contact with the extreme end of the heel, and from that point fitting the plate to the surface of the last until its front ends come in contact therewith.

It will be seen that by the use of abutments or jaws of thecharacter herein described, or which extend above the upper surface of the insole, and which hold the upper in close contact with the edge of the insole, that in the act of folding over the edge or margin upon the surface of the insole the edge or margin must advance or move inward from the edge of the insole as it is being bent over and compressed thereon, and that consequently the tting ofthe upper upon theline ofthe insole 4edge must be smooth; also, that by supporting the upper in this manner wrinkles and folds cannot extend beyond the upper surface of the insole to its edge, and this insures a perfect fitting and lasting of' the heel portion of the boot or shoe,

It is desirable that the post d should be held locked when it has been lifted to the requisite height, and I have represented as one means of accomplishing this a stop or block, p, carried by the spring p', which is supported by the standard di', adapted to close into the holes p in the post d', the block closing by springpressure automatically into any one of the ,holes desired, and thereby locking the post to the standard.

.Ihe lever a* is locked in any given position by means of the ratchet-teeth p3 and the latch p4, adapted to be carried by the lever and4 adapted to automatically engage the ratchetteeth. The latch is formed upon the end of the lever p5, and a spring (not shown) serves to keep the latch in contact with the ratchetteeth.

vHaving thus fully described myinvention,'I
